Operating limits
The following are recommended design and operating conditions for safe and effective membrane life. Operating outside these ranges may reduce effective membrane life.
- Recommended Operating Pressure: < 15.0 kg/cm² (216 psi)
- Maximum Operating Pressure: 20 kg/cm² (288 psi)
- Operating Temperature: < 35 °C (95 °F)
- Maximum Operating Temperature: 35 °C (95 °F)
- pH Range, Continuous Operation: 3 - 11 (Both feed and brine water must meet this range.)
- pH Range, Chemical Cleaning: 2 - 11
Feed water
- Feedwater Turbidity (SDI₁₅): < 5 (SDI₁₅ = Silt Density Index measured according to ASTM D4189). High flux operation on feedwater turbidity greater than 3 or 4 SDI₁₅ generally results in frequent cleaning requirements.
- Feedwater Chlorine Concentration: 0 ppm
Mechanical / hydraulic
- Feed Flow Rate per Vessel: < 650 l/h (3 gpm)
- Brine Flow Rate per Vessel: > 250 l/h (1 gpm). This figure may be reduced when there is low possibility of fouling and scaling.
- Brine/Permeate Flow Ratio: 5 : 1 (Flow ratio of brine to permeate for each single element.)
- Pressure Drop (per Element): 0.5 kg/cm² (7 psi)
- Pressure Drop (per Vessel): 1.0 kg/cm² (14 psi)
- Element(s) must be cleaned when pressure drop increases to 1.5 times of the initial value.
